Following the procedure as described in PREPARATION 2A and making non-critical variations using 5,6,7,8-tetrahydro-2-naphthol to replace 3-bromophenol, and 1-(diphenylmethyl)-1H-indole-2,3-dione to replace 1-((5-(trifluoromethyl)furan-2-yl)methyl)indoline-2,3-dione, 1-(diphenylmethyl)-3-hydroxy-3-(3-hydroxy-5,6,7,8-tetrahydronaphthalen-2-yl)-1,3-dihydro-2H-indol-2-one was obtained (76%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 8.73 (s, 1H), 7.52-7.49 (m, 1H), 7.32-7.28 (m, 10H), 7.09 (dd, J=5.6, 3.2 Hz, 2H), 6.95 (s, 1H), 6.75 (s, 1H), 6.51-6.48 (m, 2H), 4.31 (s, 1H), 2.70 (br s, 2H), 2.52 (br s, 2H), 1.72 (br s, 4H); MS (ES+) m/z 444.1 (M−17).
